应用数值方法对土壤源热泵运行一段时间后土壤温度的恢复过程进行了研究.研究结果表明,离埋管较远处土壤温度恢复较容易,而近埋管处则较难,浅层土壤温度恢复率较低,随着深度增加,恢复率逐渐增大.“,”The resuming course of ground temperature of source heat pump is simulatively researched after the ground temperature heat pump is performed for some time.The research results show that the ground temperature of far ground tubes is resumed quickly than the near ground.And the temperature resuming rate of superficial ground is lower;The temperature resuming rate is gradually increasing along with the depth of ground.
